CVE-2026-99024

The Linux kernel contains a vulnerability where optee_probe() calls tee_device_register() for both client and supplicant devices before the struct optee is fully initialized. Because tee_device_register() creates device nodes and links the device into the tee class, the device becomes accessible ...

CVE-2026-71969 OP-TEE OS 4.10.0 Buffer Underwrite via RSA NOPAD Encrypt/Decrypt Operations

OP-TEE OS through 4.10.0, fixed in commit 7b8b494, contains a buffer underwrite vulnerability in the RSA NOPAD encrypt and decrypt operations within the mbedTLS software backend and SE050 hardware driver that allows a malicious Trusted Application to corrupt secure-world heap memory by supplying ...

CVE-2026-41515

A flaw was found in OP-TEE, a Trusted Execution Environment TEE for Arm Cortex-A cores. The RSA-OAEP decryption implementation in the NXP CAAM crypto driver uses non-constant-time memory comparison for label hash verification, leading to multiple distinguishable error paths. This vulnerability...

CVE-2026-41434

A flaw was found in OP-TEE Open Portable Trusted Execution Environment, a secure environment for Arm Cortex-A cores. This vulnerability allows a local attacker with low privileges to trigger an unbounded recursion within the PKCS11 Trusted Application TA. Successful exploitation could lead to a...

CVE-2026-44362
